The voltage measured during an arc fault with the vibration test is numerized (figure 11 - Arc voltage measured). The output signal of the figure 11 represents the detection result obtained by ModelSim. The simulation result are identical for both architectures. Once a edge appears in the input signal, a peak appears at the output. The peak is positive with a rising edge, the falling edge causes the appearance of a negative peak at the output. The differences between the two algorithms concern the occupied area and the critical path of FPGA.
